The Survey looks at the socioeconomic characteristics of families and households at the national level. The latest one was conducted in February to April this year and covers a nationwide sample of about 100,000 addresses.
The increase in 25 to 34 year olds living in their parents' home began before the recent recession, and has continued in 2005 beyond it.
The report shows that the percentage of young people between 25 and 34 living at home with their parents increased from 14% in 2005 to 19% in 2011, while for young women the figures were 8% to 10% during the same period.
Beyond this, the report shows that the percentage of households with one person has increased slowly but steadily in the last half of the 20th century and continued until 21.
In 1960, the proportion of households with one person was 13% in 2011, is 28%. The figure has not changed significantly from year to year, but the direction has been upward, with a small bathroom from 2008 to 2010.
The report also reveals that in 2011, 20% of households are occupied by married couples with children, half of what it was in 1970, when 40% of the houses were occupied by married couples with children.
Also in 2007, when the recession began, the proportion of married couple family groups with children under 15 who had a mother who stays at home was 24%. That figure has fallen slightly in recent years during the recession, 23% in 2011.
